  • the invention concerns a device for fine machining workpieces, preferably for honing and/or fine boring cylinder bores in crankcases of internal combustion engines.
  • honing methods for example, peak honing, friction honing, glide honing, free-form honing, position honing, brush honing, liquid honing, laser structuring etc. All methods differ with respect to the tools, the rotary speeds, the oscillation speeds and possibly the configuration of the tools and their feed action.
  • honing machines For each honing method there are various honing machines. For example, for position honing a rotary speed of the honing tool of up to 2,000 min ⁇ 1 is required and simultaneously a stiff spindle support. For finish/plateau honing, on the other hand, a rotary speed of approximately 300 min ⁇ 1 and an articulated tool receptacle are required. When as a result of material changes or a workpiece change the honing method must be changed, the machine must be converted or another honing machine must be used.
